Abstract (en)

[origin: EP1394417A2] To provide a gas compressor improved in terms of the vane projectability at the start of the compressor. To achieve the above object, there is provided a communication passage (21;12,14) establishing communication between a high pressure supplying hole (10) and a flat groove (11) at the start of the compressor, and high pressure refrigerant gas discharged into the high pressure supplying hole (10) at the start of the compressor is supplied to the flat groove (11), whereby high pressure refrigerant gas is supplied to vane groove bottom portions, making it possible to improve the projectability of vanes. <IMAGE>
